Abstract
Description
Technical Field
[0001] This invention relates to the field of electrical appliances, and more particularly to a temperature control device for a heat-insulating and heat-resistant hair curling iron. Background Technology
[0002] A hair curling iron is a specialized electric hair styling tool. Its core consists of a heating rod, a temperature control component, and a heat-resistant handle. It uses electricity to heat the rod, and after the hair is wrapped around the rod, the heat changes the hair cuticle structure, thereby creating curls of different arcs and sizes. Some models have adjustable temperature, making them easy to use and suitable for both everyday styling and professional hair styling needs.
[0003] In existing technology, hair still retains some moisture after being dried with a hair dryer. When using a curling iron for a long time, the heating element inside the curling iron generates a lot of heat. When this heat is transferred to the moisture on the hair, the moisture evaporates rapidly and comes into contact with the scalp, which may cause burns to the scalp and damage to the internal heating element. Summary of the Invention
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A heat-resistant and heat-insulating hair curling iron temperature control device includes: a fixing mechanism, a heat-conducting mechanism, and a handle mechanism. The fixing mechanism includes a clamping plate assembly, which is divided into an upper clamping plate and a lower clamping plate. The upper and lower clamping plates are symmetrically arranged. A heat dissipation component is disposed inside the clamping plate assembly. The heat-conducting mechanism is disposed outside the fixing mechanism. The heat-conducting mechanism includes a heating component, which includes a heat-conducting plate. Two screws are inserted through the heat-conducting plate and the inner wall of the clamping plate assembly. The handle mechanism is disposed outside the fixing mechanism and includes a lower handle and an upper handle.
[0006] As a further description of the above technical solution:
[0007] The heat dissipation component includes two slots, both of which are opened on both sides of the clamping plate assembly. The inner wall of the slot is provided with a plurality of ventilation holes one, and the inner wall of the slot away from the ventilation holes one is provided with a plurality of ventilation holes two.
[0008] As a further description of the above technical solution:
[0009] The fixing mechanism also includes two mounting slots, both of which are formed at the ends of the upper and lower clamping plates.
[0010] As a further description of the above technical solution:
[0011] Both the lower handle and the upper handle are inserted into the two mounting slots. The inner walls of the upper and lower clamping plates are provided with screw holes. Screws are inserted into the screw holes, the lower handle, and the inner walls of the upper handle.
[0012] As a further description of the above technical solution:
[0013] Both the lower handle and the upper handle have friction textures on their exteriors, and a rotating assembly is provided between the lower handle and the upper handle.
[0014] As a further description of the above technical solution:
[0015] The rotating assembly includes a fixed block disposed at the end of the lower handle, a rotating shaft rotatably disposed on the inner wall of the fixed block, a perforated block disposed on the outside of the upper handle, and the rotating shaft disposed inside the perforated block.
[0016] As a further description of the above technical solution:
[0017] An elastic element is provided between the lower handle and the upper handle, and an electric wire is provided at the end of the fixing block.
[0018] As a further description of the above technical solution:
[0019] Both the lower handle and the upper handle are equipped with a heating module and a circuit module. The heating module is electrically connected to the heat-conducting plate, the circuit module is electrically connected to the heating module, and the wire is electrically connected to the circuit module.
[0020] The present invention has the following beneficial effects:
[0021] 1. In this invention, the hair straightener assembly is made of heat-resistant, heat-insulating, high-temperature silicone or modified engineering plastic. When the straightener assembly is heated, two slots of the heat dissipation component are located on both sides of the straightener assembly. When the straightener assembly is heated, heat can be discharged outward through several vent holes on the inner wall of the slots, forming an air circulation channel, thereby reducing the surface temperature of the straightener assembly. Heated water vapor is discharged through several vent holes. This structure achieves the effect of heat dissipation of the internal electronic components and water vapor discharge without contact with the scalp. It solves the problem in the prior art where, when using a curling iron for a long time, the heating component inside the curling iron generates a large amount of heat. When this heat is transferred to the water vapor on the hair, it causes the water vapor to evaporate rapidly and come into contact with the scalp, potentially causing burns to the scalp and damage to the internal heating component.
[0022] 2. In this invention, after the lower handle and upper handle are inserted into the two mounting slots, screws are inserted into the screw holes on the inner walls of the upper and lower clamping plates to securely connect the lower handle and upper handle to the clamping plate assembly, respectively, thus preventing the grip mechanism from becoming loose from the fixing mechanism. This structure achieves the effect of quick installation and removal of the lower handle and upper handle, solving the problem of inconvenient assembly of the device in the prior art.

[0028] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.
[0029] Reference Figures 1 to 4 An embodiment of the present invention provides a temperature control device for a heat-insulating and heat-resistant hair curling iron, comprising: a fixing mechanism 10, a heat-conducting mechanism 20, and a handle mechanism 30. The fixing mechanism 10 includes a clamping plate assembly 11, which is divided into an upper clamping plate and a lower clamping plate, which are symmetrically arranged. A heat dissipation component is disposed inside the clamping plate assembly 11. The heat-conducting mechanism 20 is disposed outside the fixing mechanism 10, which includes a heating component, which includes a heat-conducting plate 21. Screws 22 pass through the heat-conducting plate 21 and the inner wall of the clamping plate assembly 11. The handle mechanism 30 is disposed outside the fixing mechanism 10, which includes a lower handle 31 and an upper handle 32.
[0030] In the above embodiment, the core of the solidification mechanism 10 of this device is the clamping plate assembly 11. The clamping plate assembly 11 is made of heat-resistant, heat-insulating, high-temperature silicone or modified engineering plastic material to avoid burns caused by direct contact during use. The clamping plate assembly 11 is divided into an upper clamping plate and a lower clamping plate arranged symmetrically. The heat dissipation component inside can dissipate internal heat and heated water vapor. The heating component of the heat conduction mechanism 20 includes a heat conduction plate 21, which is fixedly connected to the inner wall of the clamping plate assembly 11 by screws 22, which can evenly conduct the heat of the heating module to the clamping plate assembly 11. At the same time, the lower handle 31 and the upper handle 32 of the grip mechanism 30 are connected to the outside of the solidification mechanism 10 to realize the gripping and opening / closing control of the device.
[0031] The heat dissipation assembly includes two slots 12, both of which are opened on both sides of the clamping plate assembly 11. The inner wall of the slot 12 is provided with a number of ventilation holes 13, and the inner wall of the slot 12 away from the ventilation holes 13 is provided with a number of ventilation holes 14.
[0032] In the above embodiment, the two slots 12 of the heat dissipation component are opened on both sides of the clamping plate assembly 11. When the clamping plate assembly 11 is heated, the heat can be discharged outward through a number of ventilation holes 14 on the inner wall of the slot 12, forming an air circulation channel, thereby reducing the surface temperature of the clamping plate assembly 11. The heated water vapor is discharged from a number of ventilation holes 13, preventing the water vapor from touching the scalp and further improving the anti-scalding effect.
[0033] The fixing mechanism 10 also includes two mounting slots 15, which are both located at the ends of the upper clamping plate and the lower clamping plate.
[0034] In the above embodiment, the two mounting slots 15 of the fixing mechanism 10 are respectively opened at the ends of the upper clamping plate and the lower clamping plate, serving as the connection carrier between the grip mechanism 30 and the fixing mechanism 10, providing mounting positions for the lower handle 31 and the upper handle 32, so that the grip and the clamping plate assembly 11 form a stable overall structure and ensure the synchronicity of the opening and closing actions.
[0035] The lower handle 31 and the upper handle 32 are both inserted into the two mounting slots 15. The inner walls of the upper and lower clamping plates are provided with screw holes 16. Screws 17 are inserted into the inner walls of the screw holes 16, the lower handle 31, the upper handle 32, and the screw holes 16.
[0036] In the above embodiment, after the lower handle 31 and the upper handle 32 are inserted into the two mounting slots 15, screws 17 are inserted into the screw holes 16 opened in the inner walls of the upper and lower clamping plates to fasten the lower handle 31 and the upper handle 32 to the clamping plate assembly 11 respectively, so as to prevent the grip mechanism 30 from loosening from the fixing mechanism 10 and ensure the structural stability of the equipment when gripping.
[0037] The lower handle 31 and the upper handle 32 are both provided with friction texture on their exterior surfaces, and a rotating component is provided between the lower handle 31 and the upper handle 32.
[0038] In the above embodiment, the friction texture on the outside of the lower handle 31 and the upper handle 32 can increase the friction between the hand and the grip, preventing slippage when holding. The rotating component between the lower handle 31 and the upper handle 32 provides rotational support for the opening and closing of the grip, so that the upper and lower clamps can open and close synchronously with the movement of the grip, meeting the clamping requirements for curly hair styling.
[0039] The rotating assembly includes a fixed block 33, which is disposed at the end of the lower handle 31. A rotating shaft 34 is rotatably disposed on the inner wall of the fixed block 33. A perforated block 37 is disposed on the outside of the upper handle 32, and the rotating shaft 34 is disposed inside the perforated block 37.
[0040] In the above embodiment, the fixing block 33 of the rotating assembly is disposed at the end of the lower handle 31, and the rotating shaft 34, which is rotatably disposed on the inner wall of the fixing block 33, passes through the perforated block 37 outside the upper handle 32. When the lower handle 31 and the upper handle 32 are gripped to perform opening and closing actions, the rotating shaft 34 can rotate with the cooperation of the fixing block 33 and the perforated block 37, so as to realize the flexible rotation of the upper handle 32 relative to the lower handle 31, thereby driving the upper clamping plate and the lower clamping plate of the clamping plate assembly 11 to open and close synchronously.
[0041] An elastic element 36 is provided between the lower handle 31 and the upper handle 32, and an electric wire 35 is provided at the end of the fixing block 33;
[0042] In the above embodiment, the elastic element 36 installed between the lower handle 31 and the upper handle 32 is the core component for the automatic reset of the grip structure. During the opening and closing process of the grip under external force, the elastic element 36 will undergo elastic deformation with the relative movement of the handle. When the external force is removed, the elastic element 36 will release the stored reset force, thereby driving the upper handle 32 to move in the opposite direction and simultaneously driving the upper clamp plate to accurately reset to the initial closed state, ensuring that the grip can quickly return to its original position after opening and closing operations, improving the convenience and continuity of equipment operation. The fixing block 33 serves as a structural connection and wiring fixing component of the equipment. The wires 35 laid at its end form a stable power transmission channel. This channel can realize the effective electrical connection between the internal circuit modules of the equipment and the external power supply, continuously and stably supplying power to the circuit modules, avoiding power supply failures caused by loose wiring connections, and providing reliable power protection for the normal operation of various functional modules of the equipment.
[0043] Both the lower handle 31 and the upper handle 32 are equipped with a heating module and a circuit module. The heating module is electrically connected to the heat conduction plate 21, and the circuit module is electrically connected to the heating module. The wire 35 is electrically connected to the circuit template.
[0044] In the above embodiment, the heating modules built into the lower handle 31 and upper handle 32 are stably electrically connected to the heat-conducting plate 21. During operation, they can efficiently convert electrical energy into heat energy. The heat is quickly and evenly conducted to the clamping plate assembly 11 via the heat-conducting plate 21, providing continuous and suitable working heat for hair styling operations and meeting different styling temperature requirements. The circuit module on the device is electrically connected to the heating module, which can detect and accurately control the working temperature of the heating module in real time, achieving constant temperature maintenance or multi-level temperature adjustment, effectively avoiding damage to the hair due to excessive temperature. At the same time, the wire 35 maintains a reliable electrical connection with the circuit module, establishing a stable power transmission channel from the external power source to the circuit module, continuously supplying power to the temperature control and heating system, fundamentally ensuring the accuracy of equipment temperature control and the stability of the entire machine's operation.
[0045] Working Principle: The core of the solidification mechanism 10 of this device is the clamping plate assembly 11. This clamping plate assembly 11 is made of heat-resistant, heat-insulating, high-temperature silicone or modified engineering plastic material to prevent burns from direct contact during use. It consists of an upper clamping plate and a lower clamping plate arranged symmetrically. Two slots 12 are opened on both sides as the core structure of the heat dissipation component. When the clamping plate assembly 11 is heated, the heat can enter the interior of the slot 12 through several vent holes 13 on the inner wall of the slot 12, and then be discharged outward through several vent holes 14 on the inner wall of the slot 12 away from the vent holes 13, forming an air circulation channel, thereby reducing the surface temperature of the clamping plate assembly 11 and further improving the anti-scalding effect. The two mounting slots 15 of the fixing mechanism 10 are respectively opened at the ends of the upper clamping plate and the lower clamping plate, serving as the connection carrier between the grip mechanism 30 and the fixing mechanism 10, and providing installation positions for the lower handle 31 and the upper handle 32. After the lower handle 31 and the upper handle 32 are inserted into the two mounting slots 15, screws 17 are inserted into the screw holes 16 opened in the inner walls of the upper clamping plate and the lower clamping plate, respectively, to fasten the lower handle 31 and the upper handle 32 to the clamping plate assembly 11, so as to prevent the grip mechanism 30 from loosening from the fixing mechanism 10, ensuring the structural stability of the equipment when gripping, and making the grip and the clamping plate assembly 11 form a stable whole, ensuring the synchronicity of the opening and closing action. The heating component of the heat conduction mechanism 20 includes a heat conduction plate 21, which is fixedly connected to the inner wall of the clamping plate assembly 11 by screws 22. This allows the heat from the heating module to be evenly conducted to the clamping plate assembly 11. The heating modules inside the lower handle 31 and the upper handle 32 are electrically connected to the heat conduction plate 21, which can convert electrical energy into heat energy and conduct it to the clamping plate assembly 11 through the heat conduction plate 21, providing the necessary heat for hair curling. The circuit module is electrically connected to the heating module, which can regulate the temperature of the heating module. The wire 35 at the end of the fixing block 33 is electrically connected to the circuit module, providing a power transmission channel for the device and enabling the external power supply to be transmitted to the circuit module, ensuring the temperature control and stable operation of the device. In addition, the friction texture on the outside of the lower handle 31 and the upper handle 32 can increase the friction between the hand and the grip, preventing slippage when holding. The rotating component between the two provides rotational support for opening and closing the grip. The fixing block 33 of the rotating component is located at the end of the lower handle 31. The rotating shaft 34, which is rotatably arranged inside the fixing block 33, passes through the perforated block 37 on the outside of the upper handle 32. When the lower handle 31 and the upper handle 32 are held and opened and closed, the rotating shaft 34 can rotate with the cooperation of the fixing block 33 and the perforated block 37, realizing the flexible rotation of the upper handle 32 relative to the lower handle 31. This drives the upper and lower clamps of the clamping plate assembly 11 to open and close synchronously, meeting the clamping requirements for curling hair. The elastic element 36 between the lower handle 31 and the upper handle 32 can provide a reset elastic force after the grip is opened and closed, so that the upper handle 32 drives the upper clamp to automatically return to the initial closed state.
[0046] The above embodiments are merely illustrative of the technical solutions of the present invention and are not intended to limit it. Anyone skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
